With the continuous improvement of the transportation capacity and the speed per hour of modern trains, the requirements on the driving safety, the stability and the riding comfort are stricter. The rail is used as a main part of rail transit and is in direct contact with wheels of a train, and the quality of the rail directly influences the safety and the stability of driving. The rail is often damaged, such as cracked and worn, due to the influence of the power action of the train, the natural environment, the quality of the rail and the like. In addition, the rails are subjected to enormous pressure from millions of tons of heavy trains shuttling on the rails each year, which also tends to deform the rails, distorting the contact surface between the rails and the train wheels. The improper wheel-rail contact surface may bring negative effects to the traveling, such as more fuel consumption, vibration noise, wheel wear, increase of maintenance workload and cost, etc., and may even lead to damage to the rail and the vehicle and occurrence of traveling accidents. Therefore, the damage to the rail must be repaired or removed in time to avoid affecting the safety of the rail transit operation. The rail is maintained and polished, so that the unevenness and the surface defects of the rail surface can be eliminated, and the rail head outline is restored to the original design requirement, thereby further developing the rail surface defects can be slowed down, the rail surface smoothness can be improved, and the aims of improving the riding comfort of passengers and reducing the noise of wheel rails can be further fulfilled.
